My guess as to the grey / blackhat tactics they used to gain initial traction were:
1) Fake "sell-side" accounts to provide marketplace liquidity
2) Manipulating app store chart ranking through bot downloads or download services to acquire "buy-side" accounts
It sounds like the service basically stopped growing once they had to abandon the black hat techniques they were using (possibly because they grew large enough to attract scrutiny from the platform operators). If that's the case, there was never a business.
